Polish and Italian get advanced language recognition system

26.01.2009
European researchers have developed the most advanced spontaneous language understanding (SLU) system for both Polish and Italian. In fact, it is the first one.

European researchers have developed the most advanced spontaneous language understanding (SLU) systems for both the Polish and Italian languages. It is the first time SLUs of this level were developed for these languages, according to the Luna project behind the work.

Spontaneous language understanding is far more advanced than the traditional interactive voice response (IVR) systems that people may already be familiar with. In traditional IVRs, the user is required to answer questions with specific words or short sentences proposed by the systems.

But with SLU, language systems are designed to respond to spontaneous speech: real conversations between people that include the sentence fillers and pause words like ‘um’ and ‘er’.

You know what I mean?

“With spontaneous language understanding, machines know the meaning of what you are saying, it is considerably more intuitive and pleasant than simple menu-driven speech applications,” explains Silvia Mosso of Loquendo in Italy which is coordinating the research.

Up to now, these sorts of systems have been unavailable in Polish or Italian, but the EU-funded Luna project has created fully functional prototypes that should be ready for commercial development shortly after the project finishes later in 2009.

To achieve this level of sophistication, the project investigated language and semantic modelling for speech understanding, and research into automatic learning, where the software ‘studies’ a series of sample conversations, called a corpus.

Finally, the scientific team looked at making the system robust and studied the portability of Luna components across the languages. The upshot is that it will be easier to take the advances developed in the project and apply them to other languages.

SLU systems already exist for languages like English and French, but Luna’s work means it will be easier to apply these techniques to a host of other languages, and Italian and Polish were a test run.

Original conversations

The polish system will be used for public transport. “People will be able to ring a public transport company and get travel information for their itinerary. The Italian system will focus on an IT helpdesk service for a public administration.

“So people will be able to call and say ‘my printer is not working,’ and they will be able to get help for that,” reveals Mosso, Luna’s coordinator. “The advantage is that these systems can be applied to other types of helpdesks, or other types of transportation.”

It will still be necessary to record the original conversations, which ‘teach’ the machine the correct responses, for any target language, but the Luna system means that it will become much easier to create high-performance automatic telephone services.

The Luna project received funding from the ICT strand of the Sixth Framework Programme for research.

This is the second of a two-part feature on Luna published by ICT Results.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
